In Montreal, a Liebherr LRB 255 piling and drilling rig is currently being used with a double rotary drive DBA 300 for the construction of an entry shaft for tunnel excavation. This application is relatively new in North America and is being executed for the first time in Quebec.

On the island of Montreal, near the intersection of Rue Notre-Dame Est and Rue Alphonse D Roy, a tunnel with a length of four kilometres and an internal diameter of 3.6 metres is planned. After completion, it will be used as a water main reaching from Montreal to the Rosemont Reservoir on Île de Montreal. The Rosemont Reservoir was shut down in 1978 and is now being put back into service in order to ensure the supply of sufficient drinking water to the city.

Secant pile wall construction
The entry shaft for the excavation of the tunnel has an interior diameter of 11 metres and is currently being constructed with the help of an LRB 255 piling and drilling rig, owned by Centurion Fondation Inc. The entry shaft is built using a compression secant pile wall made up of 74 intersecting piles, each with a diameter of 750 mm and a length of 22 metres.

The primary piles, used as filler, are installed first. Upon drilling of the secondary piles, the rebar cage is vibrated into the pile using an electric vibrator. The piles are drilled into a previously constructed template, ensuring their exact position. The soil consists of sandy clays and sandy tills with boulders and the piles are drilled approximately half a metre into the shale bedrock.
